Title: Innerseal liner for containers
Inventor: LANHAM SAMUEL E
IPC: B65D53/04
Filed: 1990-06-25
Abstract: INNERSEAL LINER FOR CONTAINERS                  Abstract of the Disclosure An innerseal liner for containers is provided which permits the removal of the entire liner from the mouth of a  container  without  any  tearing  of  the  liner.   The innerseal liner is sealed to the mouth of the container and a portion of the outer circumference  of  the  liner overhangs  the  outer  surface  of  the  mouth  of  the container.   A pull  tab  is  integrally  formed  with  the innerseal liner and at the intersection of the pull tab with the circular portion of the liner are cut-outs in the circular periphery of the liner.  The cut-outs may be arc-shaped and are of a depth approximately the same as the width of the overhang portion of the innerseal liner so that when the pull tab is pulled,  the innerseal is removed  from the mouth of  the container  along  an  arc approximately equal to the width of the pull tab and the length  of  the  cut-out  portions  before  the  overhang portion of the liner is  lifted  from the mouth of  the container.

Title: Stethoscope with diaphragm head adapter
Inventor: PACKARD THOMAS J
IPC: A61B7/02
Filed: 1990-12-06
Abstract: ABSTRACT           A stethoscope head adapter (10) for a diaphragm microphone (36) is provided.  The adapter creates a smaller surface area for the diaphragm microphone without diminishing the acoustical reception by the diaphragm (42) of normal or pathological conditions in a patient. The adapter is made from an elastomeric material to permit easy placement on the stethoscope head and to provide an effective acoustical seal against the uneven surface of the skin of a patient.  A secondary diaphragm (22) may also be provided in the adapter to focus the reception by the diaphragm microphone of the specific frequencies desired to be monitored.  With the adapter (10) on the stethoscope head (26), the intensities of sound at frequencies not desired to be monitored are attenuated when compared with the use of the stethoscope head without the adapter present.

Title: Testing the fit of a prosthesis socket
Inventor: HORVATH EDUARD
IPC: A61F2/50
Filed: 1991-02-26
Abstract: Abstract of the Disclosure The service characteristics of a prosthesis shaft for a limb stump projecting from a pivotal articulation of a patient are determined by first fitting the shaft while engaged over the limb stump into a holder pivotal about a holder axis and then aligning the holder axis so that it generally traverses the articulation. The shaft and holder are then moved by the stump pivotally about the axis to establish extreme positions of the holder that cause discomfort to the patient. Movement within the extreme positions is established as an actual-value range and compared with a desired-value range. Then the fit of the shaft on the stump is adjusted and the first three steps are repeated until the actual-value range generally corresponds to the desired-value range. Normally the holder is pivotal about two generally perpendicular and coplanar holder axes and the intersection of the axes being set generally at the articulation.

Abstract: A multi-sample multi-channel decimator producing a FIR filtering response from 128 digital filter coefficients for 4 independent channels with a decimation ratio of 32, i.e. from 1MHz 1-bit inputs to 32 kHz multibit outputs, splits cyclically the coefficient values in 16 groups of 8, according to the coefficient positions, into 4 ROMs (0, 1, 2, 3).  The ROMs are coupled to the 4 multipliers (MULT 0, 1, 2, 3), wherein the coefficient value is multiplied by that of the input bit, through a multiplexer (MUXI) able to cycle through 4 distinct conditions.  After the 4 adder accumulators (ACC 0, 1, 2, 3) coupled to the outputs of their respective channel multipliers have, in parallel partially computed output words, each using one sixteenth of the coefficients, the multiplexer rotates these, thereby enabling complete computation in 4 cycles, 4 registers (REG 00, 01, 02. 03) being associated to each adder so as to compute 4 staggered output words simultaneously for each channel.  A preferred filtering response can reduce the size of the ROMs.

Abstract: In a receiver an apparatus and method substantially reduces time dispersion and multipath distortion in a received signal. An equalizer (109), including taps having gain coefficients, produces an equalized signal (110) responsive to the received signal (107) and an adaptive process signal (137), wherein the gain coefficients are adjusted responsive to the adaptive process signal (137). A first mixer (111) mixes the equalized signal (110) and a reference carrier signal (115) to produce a recovered modulated signal (119). A detector (112) detects an estimate signal (129) responsive to the recovered modulated signal (119). An error signal generator (139) generates an error signal (141) responsive to a difference between the recovered modulated signal (119) and the estimate signal (129). A second mixer (147) mixes the error signal (141) and the reference carrier signal (115) to produce the adaptive process signal (137). In a preferred embodiment, a third mixer (153) mixes the estimate signal (129) and the reference carrier signal (115) to produce a feedback signal (135) for at least one tap. The present invention advantageously permits the equalizer (109) and the detector (112) to optimally perform their respective functions while coupled together to maximize the receiver's performance.

Abstract: A digital switching network for providing simultaneous connections  among  user  processors  of  processor-based communications  equipment.   The user processors act as originators  and  destinations  of  data  communications packets.    Packet  data  connections  are  through  node controllers, which communicate with gateways, which are connected to a switching network via packet links.  Control messages  are  communicated  between  node  controllers, gateways, and an interchange control subsystem via various control message links.  All control message processing and packet data transmissions are synchronized with a packet frame  synchronization  signal,   and  processing  tasks performed by each of the network subsystems are pipelined so that they occur simultaneously.  Service requests are queued  in a central  queue  in the  interchange control system.   The synchronization and queueing simplify the control messages that are required to set up and release the connections.

Title: Nested-cone separator
Inventor: THILLY WILLIAM G
IPC: C12N5/071
Filed: 1990-11-02
Abstract: A cell culture system is presented for separation of cells from perfusate in a cell culture. Perfusate and cells suspended by the perfusate are directed through a nested-cone separator having an outer cone and an inner cone defining an annulus which forms an expanding cross-sectional area of flow whereby the velocity of perfusate within the annulus diminishes with distance from the suspended cell culture. The superficial velocity of the perfusate is thereby reduced. A Boycott effect and diminished superficial velocity within the annulus allow cells which are to be returned to the suspended cell culture to thereby settle across the path of perfusate flow in the annulus and to return to the cell culture.  Perfusate is separated thereby from cells and is removed from the cell culture while allowing highly reliable and cost-effective control of cell cultures for prolonged periods of time.

Abstract: An interface apparatus (12) and method for transmitting data between a host computer (16) and a telecommunication network (11) without requiring special host-based computer programs to communicate with the interface apparatus (12). The invention uses existing ports of the host computer (16), utilized in their standard method of operations, such as driving a printer (18) or communicating with a workstation. This reduces cost, simplifies use, and permits the use of the telecommunication interface apparatus (12) with any computer utilizing its existing programs. The interface apparatus (12) scans the beginning of a message for a command code comprising a string of special characters and the adressee number and/or code. If such a code is detected, the message is transmitted over the telecommunication network (11). Otherwise, the message is passed through the interface apparatus (12) unchanged to be printed or otherwise output.
